I don't think it is necessary to replace all `#if KMP_USE_HWLOC` by the new macro, but I don't see how it would be harmful. All uses of `__kmp_hwloc_topology` should be sufficient to fix the compilation issue. For testing the changes on a non-darwin platform, it should be sufficient to just modify the `#define KMP_AFFINITY_SUPPORTED 1` in kmp_os.h to set the value to 0.

How about `KMP_INCLUDES_HWLOC` as name for the new define?
